SHAFT-HANGER.

Specification of Letters Patent.

Patented. Nov. 19, 1907.

Application filed October 18. 1905- Seria1No.283.2'76- To all whomit mayconcern:

Be it known that I, ELMER E. MCINTYRE,

citizen of the United States of America, residstruot shaft hangers ofnovel construction of pressed or forged steel.

My invention aims to provide a hanger in which a shaft may be adjustablymounted and in connection with the hanger and the adjustable shaft"bearing, I employ novel means for preventing longitudinal displacementof the shaft when journaled in said hanger.

With the above and other objects in view, which will more readily appearas the nature of the invention is better understood, the same consistsin the novel construction, combination and arran ement of parts to behereinafter more fully described and then specifically pointed out inthe claims, and referring to the drawing accompanying this application,like numerals of references designate corresponding parts throughout theseveral views, in which:-

Figure 1 is a side elevation of my improved hanger,Fig. 2 is a frontelevation, Fig. 3 is a vertlcal sectional view of the han er, Fig. 4 isa side elevation of a detachable bearing support, Fig. 5 is a front viewof the same, Fig. 6 is a cross sectional view of one of the depending les of the hanger, Fig. 7 is a plan of the cross T1ead of the hanger, Fig.8 is a side elevation of one of the legs of the hanger, Fig. 9 is afront elevation of the same, Fig. 10 is a plan of the tie plate of thehanger, Fig. 11 is a side elevation of the bearing or journal box ofthehanger, partly in sectlon, Flg. 12 is an end elevation of the same, Fig.13 is a plan of the lowermost part plan view of the journal boX, Fig. 14is a side elevation of the bearing block of the journal box, Fig. 15 isan end view of the same, Fi 16 is a top of the bearing block, l i 17 isa plan view of the blank employed in constructing the legs of thehanger, and Fig. 18 is an end view of the legs of the hanger.

To put my invention into practice, I employ two steel plates or blanksas shown in Fig. 17 which are bent to form legs 1, each leg beingsubstantially T-shaped in cross section and comprising a web 2 andoppositely projecting flanges 3. Each leg tapers and has its largest endformed with pierced horizontal flanges 4 forming bearings for the u percoupling plate as hereafter described, whlle the smaller ends of thelegs are pierced as at 5. The flanges 3 intermediate the ends of eachleg are provided with apertures 6. The legs 1 are suitably secured to atie plate 7, by means of the bearings 4, said legs being positioned uponsaid tie plate whereby the flanges 3 of each leg will confront oneanother. The tie plate 7 is pierced as at 8, to permit of the bearings 4being secured to the tie plate by rivets 8. The tie plate 7 is slottedas at 8 in order that the hanger may be adjustably secured to a ceiling,overhead beam or girder bolts and nuts 8, said bolts passing through theslots of the tie plate 7.

The intermediate portion of the tie plate 7 is depressed to formdepending shoulders bearing against the inner edges of the flanges 3 andthus serving as a spreader between the legs of the device, andeffectually preventing a tendency of the legs to be collapsed by anypressure to which they may be subjected.

Mounted between the legs 1, and secured to the flanges 3 by rivets 9 isan intermediate cross head 10, said head being formed with a centralvertically disposed boss 11 having an opening 12 formed therein. Mountedin said opening is a screw 14 having a head 15 and said screw isadjustably retained within the boss by a jam nut 18, which bears uponthe top of said boss, as clearly illustrated in Fi s. 1 and 3.

ecured to the lower pierced ends of the legs 1, is a bearing support 19,said support being substantially semi-circular in form and havingbifurcated pierced ends 20, 20, said ends being secured to the ends ofthe legs 1 by nuts and bolts 21. The upper edge of the bearing supportis formed with flanges 22, the upper edges of which engage the flanges 3of the legs when the bearing support is socured to said legs. Thebearing support is formed with a central vertically disposed boss 23having a screw threaded opening 24 formed therein, and in said openingis mounted a screw 25 having a head 26 and a lock nut 27 The screw 25 isadapted to vertically aline with the screw 14 of the intermediate crosshead. 10. 4

A journal box 28 is mounted between the screws 14.- and 25. The journalbox is clearly illustrated in Figs. 3, and 11 to 16 inclusive. The boxconsists of an outer casing formed in two parts 29 and 30, each partbeing substantially semi-cylindrical in form, the part 29 being adaptedto fit upon the part 80. The part 30 of the journal box is formed with acontracted center portion 31 providing semi-circular shoulders 32, andwhen the part 30 is mounted between the legs 1 and the screws 14 and 25,the shouldersv 32 are adapted to engage the edges of the flanges 3 ofsaid legs. The part 30 is rovided centrally of its length with anenargement 33 which extends within the contracted portion 31 of the part30 and also outside thereof and in the outer side of the enlargement isformed a recess34 in which the upper end of the screw 25 is adapted toseat.

The part 29 is provided with a lining of Babbitt metal and this liningis provid ed with substantiallysemi-circular slots 29 adjacent to itsends, while the ends of the part 29 are provided with semi-circularrecesses 29". The part 29 at each end is provided with oiling ports 35which permit of oil being placed in the part 29. Centrally of the top ofsaid part 29 is formed an enlargement or boss 36 having a semi-sphericalrecess 37 formed therein, to receive the end of the screw 14-.

In the lower part 30 of the journal box is mounted a bearing block 38which is cylindrical in form. The bearing block is preferably made outof pressed steel having a lining of Babbitt metal and centrally of itslength is provided with a recess 39 to receive the enlargement 33 formedupon the inner 'side of the. part 30. I In the bearing block issupported the shaft or axle 40 to be journaled in the hanger. The curvedinner sides of the bearing block are provided with diagonally disposedgrooves 41, 41, these grooves being adapted to convey a lubricant to thebearing surface'of the shaft 40 which frictionally en- "age the curvedsidesof the bearing block. urrounding the bearing block 38 and. theshaft 40 at each end thereof is a chain 44- said chain being looselymounted upon the shaft and passing around in the slots 29 and through alubricant receptacle 33 formed in the bottom of the part 30 of thejournal box. Oil is admitted to the lubricant receptacle through theports 35 said lubricant passing around the ends of the journal box.As'the shaft revolves the chains 44 are adapted to convey oil or thelike lubricant from said receptacle to the top of the shaft where itwill be distributed. The lower part 30 of the journal box is providedwith an upwardly extending lug 44 at each end thereof which 13 adaptedto engage the shaft and prevent the lubricant from caking or becomingcoated upon the shaft in the oil passage at each end of the ournal box.

It will be observed that the different parts of my improved hangers areconstructed of pressed steel, and that these parts can be easily andquickly assembled to provide a strong and durable bearing or hanger fora shaft or axle. It is possible to adjust the journal box of the hangersat any desired time the shafting or axles journaled in the boxes needalining, this being accomplished by the screws of the hangers.

I desire it to be understood that each and every part of my improvedhanger, with the exception of the chains 44 and the Babbitt metal lining29*, are made of pressed or forged steel and by so forming said parts, Ican manufacture my improved hangers. at a comparatively small cost andwith the least expenditure of labor necessary to produce hangers.

The. blank A, shown in Fig. 17 is folded and pressed along the dottedlines a, to form the web 2 consisting of two thicknesses of metal, andthe laterally extending flanges 3. The legs are firmly braced andreinforced by the central webs.
